This invention relates to improvements in electrical insect destroyersand more particularly to devices of this description in the form ofscreen doors, and the objects of the invention are to provide a simpleand durable device of this description which can be manufactured at lowcost and placed on the market. in large quantities.

With the foregoing and other objects in view, the invention consistsessentially .1n a screen or the like comprising double screen sections,preferably of metal, including casings' intermediately woven with aplurality of wires adapted to be rigidly secured to one another andhaving suitable insulating 'means therebetween, the wires beingintermediately supported in said casings by spaced insulating bars orthe like, and sepa- -rate electrical means for connecting the wires ineach section to the source 01 electrical power, whereby on an insectendeavouring to pass through said double screen it. contacts with thewires in each section to close the circuit, thus being immediatelyelectrocuted, and insulated means for securing the sections together.

Referring to the drawings, in which like I characters ofreferenceindicate corresponding parts in each figure;

This screen consistsessentiallv of two frames 1 and 2 preferably ofmetal, and these sectionsin turn are provided withfscreening inflthe form of a plurality of wires'5 and "6 forming two distinct sets adapted to be separately connectedthrough connections 12 with a -source of electrical power.

2, that when the sections are secured together the individual wires ofthe difi'erent sets or screen carried thereby will be in staggeredrelationship to one another to more efi'ectlvely ensure that an msectendeavouring to pass through the screens will contact immediately withone of the-wires carried by each section. The wires are insulated andconnected as at 12 to the different poles of a source of ele tric powerso that being insulated from o e another and each connected to one poleof a source of electricity, the

circuit is not closed until the insect, en

deavouring t9 pass through the screen, closes it and thus charges thewires.

From the foregoing, the simplicity and effectiveness of mydevice ascompared with electrical screens and electrical insect destroyersheretofore in use will be apparent.
